About This Root

From Latin co- ('together, thoroughly') intensifying two verbs of mental work: cōgitāre ('to think, turn over in the mind,' from co- + agitāre 'to drive/stir') and cognōscere ('to get to know, recognize,' from co- + gnōscere 'to know'). The cog/cogit/cogn forms all describe processing something thoroughly in the mind — whether thinking it over (cogitate, excogitate) or coming to know it (recognition, cognizance).
